I'm not a pro, don't shoot every day or even every week, so the 1-2tb drives are fine for now. Internal data drive is backed up to external HD1 which is backed up to external HD2 and so on. It is crude and slow, but I figure at least one HD will live, especially since they are disconnected from power and PC until used, and at least one is locked up. With regard to more elegant solutions, I know that at our firm with have "storage area networks". Each one nets to about 1.5tb of storage and has lots of hard drives. Each one costs about $7,000 (I have tried to will the exact amount out of my mind). There may be something in between "one might fail" and "can not fail". We have drives that fail, but no user knows it. Ken Cheapskate
